CFR /  Title 40  /  Part 141  /  Sec. 141.564 My system practices lime softening--is there any monitoring?

If your system utilizes lime softening, you may apply to the State for alternative turbidity exceedance levels for the levels specified in the table in Sec. 141.563. You must be able to demonstrate to the State that higher turbidity levels are due to lime carryover only, and not due to degraded filter performance.
